Vehicle magnetic field calibration:
The Dakota Digital compass has a calibration procedure to compensate
for the vehicle magnetic field. This magnetic field is produced by the hard iron of
the vehicle as well as any electric accessories which are operating. This
calibration should be done with the engine running as well as any accessories
which are normally used. It is best to do the calibration in an open area so that
there is no interference from nearby vehicles or power lines.
1. Make sure the ignition key is off so the compass is not lit up.
2. Hold in the button located on the front of the bezel while you start the
engine.
3. After the display lights up, release the button. The display will show a
number.
4. Press and release the button until “CAL” is displayed.
5. Press and hold the button. The display will show “CALIBRAT”.
6. Release the button. Once the compass has taken its initial reading, it
will display “TURN 180”.
7. Move the vehicle so that it is facing the exact opposite direction.
8. Press and release the button, the display will show “WORKING” and
then “COMPASS”.
9. The unit will now return to normal operation.
